Show 320 MR. P. L. SCLATER ON NEW AMERICAN BIRDS. [May 22, 5. Descriptions of Six New Species of American Oseines. By P. L. SCLATER, M.A., Ph.D., Secretary to the Society. 1. TURDUS SUBCINEREUS, sp. nov. Supra obscure cinereus, alis caudaque fuscis, extus cinereo marginatis : subtus albo-cinereus, gutturis et pectoris plumarum rachidibus fusco-cinereis, crisso fulvescente lavato ; subalari-bus cinerascenti-albis fulvo vix tinctis : rostro corneo; mandi-bula inferiore pallida ; pedibus obscure fuscis: long, tota poll. Angl., alar 4'6, caudar 3*8, rostri a rictu 8*5, tarsi Hab. (ut dicitur) in rep. Chiliana. Mus. P. L. S. Obs. Affinis T. chiguanco, Lafr. et D'Orb., et fere ejusdem formae, sed statura valde minore, pectore obsolete striato et subalaribus non cinnamomeis distinguendus. I have a single skin of this Thrush in my collection, purchased of M. Verreaux of Paris, and marked " Chili." I have not met with other specimens. The species is not very closely allied to any other that I am acquainted with, but seems to go best in the series allied to Turdus chiguanco. The first (or spurious) primary is rather large, measuring 1*5 inch from the insertion. The fourth and fifth primaries are equal and longest, slightly exceeding the third and sixth. The bill is rather short and more compressed than in most species of the genus. 2. CINCLOCERTHIA MACRORHYNCHA, sp. nov. Supra obscure cinerea, fere unicolor, capite prarcipue ad latera nigricantiore : subtus lactescenti-alba, pectore et crisso lateribus et subalaribus fusco-cinerascentibus : rostro paulum incurvo, nigro; pedibus corylinis : long, tota 10*5, alar caudar 3'3, rostri a rictu (lin. dir.) 20, tarsi \'\5. Hab. in ins. S. Lucia, Antillensium (Bonnecourt). Mus. Parisiensi. Obs. Species a C. ruficauda corpore supra omnino cinereo, a C. gutturali colore corporis inferi dilutiore, ab utraque rostro elongato incurvo distinguenda. This bird forms a very distinct third species of the Antillean genus Cinclocerthia, of which two species are given in mv " Synopsis of the Turdidee" (P. Z. S. 1859, p. 338). As we should have expected, it comes from a different island from those which the other two species inhabit. While C. ruficauda is found in Nevis and Guadeloupe, and C. gutturalis in Martinique only, as far as we know, the present species is from the island of Santa Lucia. I am indebted to my friend M. Jules Verreaux, Aide-Naturaliste to the Museum of Natural History at the Jardin des Plantes, for the opportunity of describing this species-the only specimen I have yet met of it occurring in that collection, to which it was transmitted by M.Bonnecourt in 1850. |
